Good morning Technetters.
I am having some occasionally voids/pin holes on our PBGA. We are currently
using NC293 Sn63/Pb37 Aim solder paste. The board is silver plated. Printing
with a 6 mil stencil.
Is it normal to have occasionally voids?
We have bake our PBGA's prior to reflow, and also work with the oven
profile. Any suggestions.
Thank you
